Using A Tracert Command To Identify Failed Or All Nodes In A Path; System Debugging; Debugging Information Control Switches - HP 5500 EI Series Configuration Manual

• Enable sending of ICMP destination unreachable packets on the destination device. If the
destination device is an HP device, execute the ip unreachables enable command. For more
information about this command, see Layer 3—IP Services Command Reference.
If there is an MPLS network between the source and destination devices and you need to display the
•
MPLS information during the tracert process, enable support for ICMP extensions on the source and
intermediate devices. If the source and intermediate devices are HP devices, execute the ip
icmp-extensions compliant command on the devices. For more information about this command,
see Layer 3—IP Services Command Reference.
For an IPv6 network:
Enable sending of ICMPv6 timeout packets on the intermediate devices (the devices between the
•
source and destination devices). If the intermediate devices are HP devices, execute the ipv6
hoplimit-expires enable command on the devices. For more information about this command, see
Layer 3—IP Services Command Reference.
Enable sending of ICMPv6 destination unreachable packets on the destination device. If the
•
destination device is an HP device, execute the ipv6 unreachables enable command. For more
information about this command, see Layer 3—IP Services Command Reference.

System debugging

The device supports various debugging for the majority of protocols and features and provides
debugging information to help users diagnose errors.

Debugging information control switches

The following two switches control the display of debugging information:
• Protocol debugging switch—Controls protocol-specific debugging information.
Command
•
For an IPv4 network:
tracert [ -a source-ip | -f first-ttl | -m max-ttl |
-p port | -q packet-number | -tos tos |
-vpn-instance vpn-instance-name | -w
timeout ] * host
•
For an IPv6 network:
tracert ipv6 [ -f first-ttl | -m max-ttl | -p port |
-q packet-number | -tos tos | -vpn-instance
vpn-instance-name | -w timeout ] * host
